Project Description
The project consists of three separate tasks at the Boeing main Renton
plant and at the Renton Municipal airport.
Replace sewer lift station near 4-42 Fuel spill containment at Apron D,
Modify D-50 gate entrance
Task one Replace sewer lift station near 4-42,
Replace sewer lift station is just west of the 4-42 bldg underneath the Boeing
internal roadway on the east side of the Cedar River
Task two Fuel spill containment at Apron D,
Fuel spill containment at Apron D is near the Boeing south bridge adjacent to the
Boeing access road east of the river
ENVIRONMENTAL CHECKLIST 3
6/30/2017
Task three Modify D-50 gate entrance
Modify D-50 gate entrance is adjacent to East. Perimeter road and west of the
Cedar River on Boeing leased airport property.
Task one
Replace sewer lift station near 4-42
Scope of Work
The scope of work for this task involves replacement of Building 4 -42
sewage lift station. This lift station serves Building 4 -42, 4-41 and west side
of Building 4-20.
The new lift station shall be constructed and readied to place on line. During
an outage, the sewer pipes shall be switched from the old lift station to the
new lift station without impacting the building operations. Design of the new
lift station shall take into effect the need to keep the buildings operational
except for the switchover. Reroute existing fire line for new lift station
The scope of work includes installation of a new vault for collection of
sewage, two new submersible sewage pumps, controls and piping. A new 8”
sewer line from sewage collected from Building 4-42 and 4-41 will be
rerouted to the new 8 ft. sewage lift station vault.
A 48” diameter manhole will be installed to collect the sewage upstream of
the new vault The 4” discharge line from the new sewage pumps will be
connected to the existing 4” sewage discharge line just south of the new lift
station.
The old sewage lift station will be demolished and filled in after the new lift
station is put into service. Impervious surface disturbance is approx. 1900
sq. ft.
ENVIRONMENTAL CHECKLIST 4
6/30/2017
Task Two
Fuel spill containment Apron D
Scope of Work
The project will add a new fuel containment to the Boeing Apron D which
is used for 737 Aircraft stalls. The system is designed to capture any fuel
that may be spilled on the apron in an underground holding area.
To allow for control and isolation of the storm water flow paths in the event
of a spill, the existing 72” storm drainage a manhole will be replaced with an
84” storm drainage manhole. The replacement will allow for the installation
of valves to direct the storm drainage flow.
To contain any potential fuel the project will install 2 each new 5000 gallon
fuel spill containment tanks
The project will replace several short (approx. 7LF each) sections of existing
24 & 12 diameter pipes.
The system is being designed to maintain the current operating conditions of
the existing system only making modifications to allow for containment and
isolation of potentially fuel laden storm flows. The hydrology of the
normally operating system will not be impacted by this project.
The project will then replace 840 sq. ft. of existing Asphalt pavement, and
750 sq. ft. of concrete pavement for a total of 1,590 total replaced pavement
Task 3
Modify existing Boeing Gate D-50 entrance to add a pedestrian
walkway path
Scope of Work
